Oh! Of course there is!! As long as there are human beings better than others and a lot of means much better than before; so of course there is BUT on the condition of having a strong will.. "Where there is a will, there is a way" Salam!

You can change your own world not the surround one.This is to say , you can create the world in which you wanna live by adhering to your own ideas and beliefs by being yourself.However , you can not change all people according to your own vision . You can only select people whose ideas are a likeness of yours to deal with them.

Sure,I think positively.You can compare the past with the present.So it's the same betweem now nd future.Everything's getting better,though there are many deficiencies,the world at least is developing,no matter how slowly.

maybe u can change around the environment, but can't change people's minds change the world needs time, need all people so im not sure it depends on our own

ya if there r achance inside urself sure thers another one outside the chance inside the mankind not n the circumestences
